C Pap Pillow for use with all PAP therapy, masks and brands. Minimizes mask leaks. Custom side cutouts improve mask fit and reduce mask interference and slippage. Choose your own comfort. One pillow, two choices: ventilated memory foam with cool 3D mesh cover on one side or plush fiberfill for the feel of a traditional pillow on the other. Hose tether keeps weight of the hose from pulling on the mask and allows the user to move easily throughout the night. Concave center for your head, crescent cutout for your shoulders and facial support on the sides for easy breathing and improved positioning. Remove layers to choose your comfort level.
